Yes, that's right, this is the last message and they opened my account after that without any problems, and it was closed again on 7/19/2024
Well, to be fair, that could mean they just investigated further into your case recently, as in it was brought back to their awareness that your previous one was rather inconclusive instead of resolved, and someone made a mistake by unlocking it before any investigation was completely done.
It should come in logical line with their explanation that they found your account and affiliate program rather... ill-natured.
Quite frankly, we can't --of course-- prove their claim that your account spreads malware through [I can only infer, from the nature of this case] the affiliate link and how you redirect the visitors and players. Just like we can't take your words at face value that all you do is legit and not ill-natured.
Normally, with a direct and a more stable means of communication with casino's representative, I'll pursue to get to the bottom of cases, find the real truth. But, headache-inducing and time consuming as this case is, especially with the difficulties to reach them, I am proposing you both to agree to disagree, say your goodbyes, and both to take their way. In other words, you both stopped working together; you stopped promoting them, remove all of the affiliate program from your social media, and they, well, pay you what's yours.
In short, instead of inquiring them many things to prove their claim, why the account got unlocked back in 2022 if they're still inconclusive, why re-locing it just now, etc., I'll just ask them to perhaps [given there is no financial damage on their side that require certain amount from your account to be reabsorbed to recuperate] give you whatever left on your account. I can't promise you that they'll accept this proposal, but suppose I can make this work, will you?
